How long does it take for 2 units of botox to wear off (directly under eye)?

I use Botox under the eye all the time and I find the low dose injections  last around 4-6 weeks approximately. If you have an issue or question You should call your doctor for a reevaluation because maybe you just need more Botox to reduce the other lines. 

The good news is this will go away. The bad news is that there is nothing you can do to make it happen faster. I'd hope just 2 units would be gone within 4-6 weeks. Hang in there. "This answer has been solicited without seeing this patient and
